Doesn't work for me.

[ 0.000000] Malformed early option 'earlycon'

That functionality is implemented by param_setup_earlycon and
early_init_dt_scan_chosen_stdout. Check why those aren't built into
your kernel.

OpenEmbedded passes "earlycon=sbi", which I can find in the doumentation. I can't find anything about just "earlycon". I've sent a patch adding sbi to the list of earlycon arguments.
